Why not a knee switch?

 

You've heard of a thumb switch, palm switch, foot switch and 2-hand safety switches.  I invented (or rather simply adapted) a knee switch. 

 

Because it works.

 

We have this polybag sealing machine.  We stuff the product in the bag; align the open end of the bag neatly with both hands.  Place it in the sealing strip and step on the foot switch.  If only the foot switch stays in one place all the time.  You see, when people are working and moving around a machine they keep shoving things around with their feet by accident.  And one of these things that get shoved around is the foot switch.  So when an operator gets the product and polybag together into the machine and steps on nothing, she gets frustrated.  So, along comes Mr.'Mcgyver' with a quick solution.  Got some cello tape and stuck the switch on the leg of the machine stand, at about the height of the operator's knee.  Presto!  That's the knee switch.  Repeat the above procedure with the product and polybag and then shove the switch with the knee.  The bag gets sealed neatly and in the exact location.  End of story.

 

But no!  The smart alec with his better-than-thou and safer than safe policy (full of concern for his workers) wants 2-hand safety.  C'mon, whoever heard of a worker, with both eyes open, sealing her fingers together with a polybag?  This guy's never heard of such thing as a knee switch.  Doesn't give a damn about efficiency and non-conventional methods.  Just follow standard practice.  So, innovation goes out the window.  Along with the enthusiasm of the 'outside the box' thinker.

  1. How? So now the operator has to use BOTH hands simultaneously to activate the machine?

  6. Hmmm... knee switch and rollers don't mix well, I reckon...

  7. these rollers (casters) can be locked. besides the switch is triggered only by slight touch. Imagine a pc mouse with the whole top cover as the button.

  8. That's what they don't get...I used only a bit of my brain. They didn't pay me to work like this...They want elaborate looking devices that can impress visitors. This probably embarrassed some people. Enough said.

  9. then they should get an industrial/product designer...
    aesthetic+function+technology (quoted from my uni lecturer)

  10. nah... after calculating the costs they'd simply say, 'just make things simple, ok?'
    So the guys in equipment fabrication just employ the "cut and paste" technology. Period.
